SCRAPER.

To aZZ whom it may concern:

Be it known that l, CHARLES B. Routiers, a citizen of the United States,residing` at Modesto, in the county oi' Stanislaus, State ofaCalifornia, have invented certain new and useful improvements inScrapers; and l do declare the following to be a clear, full, and exactdescription of the same, such as will enable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the characters of reference markedthereon, which form a partot this application.

This invention relates to improvements in Scrapers and is particularlydesigned as a wheel scaper, the object of the invention being to producea wheel scraper in which the wheels are adapted both to carry the loadwhen the scraper is full and also to act as a substitute for runners newcom* monly used when the sc'aper is being emptied.

A. further object is to produce an easy and eiective means for raisingthe scraper from scraping position onto the wheels when it is loaded andsimultaneously closing the iront oit the scraper to prevent the dirtfrom talling out.

The invention then further embodies a quick and effective means torthrowing the scraper into dumping position andthen returning all oit'the parts to normal carrying or loading position as may be desired.

A still further object of the invention is to produce, in conjunctionwith the above mechanism, suitable adjustments for preventing thescraper from tipping too iar or become hard to handle and further toadjust it so as to spread the dirt thick or thin or in one heap or pileas may be desired.

A further object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedingly eil'ective for the purposesfor which it is designed.

These objects, l accomplish by means ot such structure and relativearrangement ot the parts as will fully appear by a perusal of thefollowing specification and claims.

0n the drawings, similar characters oi. reference indicatecorresponding1 parts in the several views.

sition. Fig. 3 is a similar view as it appears in dumping position. Fig.l is a top plan view of the scraper.

ite'lerring now more particularly to the characters oi reference on thedrawings, I first provide two carrying arms 1 provided with upwardlyextending portions Q. In the outer ends ot the arms 1, as at 3, arenormally carried turnable wheels Li. Just back of the points at whichthe arms 1 carry the wheels li, l pivotally mount a scraper on said arms1 as at 6.

Flexibly connected with the sides oi the bowl 5, below the pivotal pointt3, are draw bars 7 projecting a distance beyond the front oi the bowland rigidly joined at their outer ends by means ot a cross beam 8. Themember 8 is provided with a centra downwardly projecting supportingmember 9 having a ruimer shoe 10 on its lower end. Frojecting upwardlyfrom each draw bar 7 is a stop iraine or arm 11 for the purpose as willappear.

Fivotally mounted to each side of the `bowl 5 above the pivotal point 6,as at 12, is an arm 13, such arms having a cross bar 111.- carrying aclosing door blade 15, capable, when the arms 13 move on 'their pivotalpoints 12, to drop down over the front ot the bowl 5 to form a closingdoor tor the same when it is in carrying position as shown in Fig. 1.Flhen in loading position as shown in Fig. Q, this door 15 is heldnormally open by means ot a chain 16 connected from the member 11i to across member -17 on the members 2. Said member 17 is provided withv anoperating lever 18. ris will A,be noted when the scraper is in loadingpo sition as shown in F 2, the Wheels Li are held clear of the ground bymeans of the arms 1 and 2 being in their normal backward position. Thenwhen the scraper is loaded and is to be. carried, the lever 18 isoperated to move the arms 1 and 2 on the pivotal point G which bringsthe wheels 'i against the gro-und and then by continuing` the movementoit the lever 18, this will litt the bowl clear of the ground and causeit to be suspended and carried on the wheels i and shoe 1() as shown inFig. 1. This same action of course loosens the chain 16 to permit thearms 13 to drop down to causethe door 15 to close in front ci the bowlto prevent the dirt from falling out. The arms 1 and 2 are also broughtto a stationary iixed position to hold the bowl 5 suspended to ride onthe wheels 4 by means of the member 17 coming in contact with the stopmembers 11. After the bowl is loaded and carried to the point desired asabove set forth and it is desired to empty the same, a lever 19 on theback side of the bowl is operated to swing the bowl on its pivotalconnections with the arms 1 to tip the said bowl to inverted position asshown in Fig. 3. lhen this action takes place, the cross member 14 restsagainst the member 7 and is prevented from moving with the bowl for thisreason, hence, the said door 15 is opened away from the end of the bowlto permit the dirt to be emptied therefrom.

Pivotally mounted on the rear of the bowl 5 is a latch member 20. Whenthe bowl is tilted to emptying position as shown, this latch member isthrown over and engages the member 17 as it rests on the members 11.Then when the bowl is pulled back to carrying position again, this latchalso brings back the member 17 carrying the arms l and 2 andincidentally the wheels l into tie position shown in Fig. 2 and by meansof the chain connection 16 the member lil Carrying the door 15 is alsobrought back to open position leaving the scraper ready to be filledagain, lllhe latch Q0 when engaging the bar 17 of course locks the bowl5 in the position in which it is dumped so that it cannot tilt forwardor backward until brought back in the manner desired. Also by making thelatch 20 adjustable the angle at which the bowl is held tilted indumping position could be varied to spread the dirt in a thick or thinlayer or pile as might be desired.

At the rear ends of the upper edges of the sides of the bowl, I providestop members 21 and at the lower ends of the front edges of the sides ofthe bowl, provide stop members 22. These stop members, by striking` themembers 7 limit the tilting movement of the bowl forward or backwardrespectively,

From the foregoing description it will readily appear that my improvedscraper embodies the following features, namely, a scraper bowl, meansfor quickly and easily Vraising the bowl onto carrier wheels when loadedand closing the front of the scraper to hold the dirt therein, means forquickly tilting the bowl to emptying position and simultaneously openingthe door and further a means for returning all of the parts to normalloading position again. From the foregoing description it will bereadily seen that l have produced such a device as substantially fulfilsthe objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferredconstructionL of the device, still in practice, such deviations fromsuch detail may be resorted to as do not form a departure from thespirit of the invention,

Having thus described my invention what l claim as new and useful anddesire to secure by Letters VPatent is:

A. device of the character described comprising a scraper bowl, a pairof arms pivotally mounted on said scraper bowl and carrying wheels ontheir forward ends and a cross bar on their rear ends, draw barspivotally mounted in said scraper bowl and being supported at theirouter ends, an upwardly projecting stop member on said draw bars, meansfor moving said arms on their pivotal points to cause said cross bar toengage said stop member and to cause said wheels to engage the groundsurface whereby said scraper bowl will be held suspended between saidarms, a closure held normally away from the frontV of said scraper bowlbut adapted to move in front thereof when the same is so suspendedbetween said arms, means for tilting said scraper bowl on its pivotalconnection with said arms to throw it to inverted emptying position,said closure engaging and being held from further movement by said drawbars when said bowl is so tilted to said inverted position, a chainconnecting said crossbar and said closure, and a latch pivotally mountedon said bowl and adapted to engage said cross bar when said bowl ismoved to said inverted position, as described.

ln testimony whereof I affix my signature in presence of two witnesses.
